In a coal fired power plants, coal mill or coal pulverizers are used to pulverize and dry the coal before it is blown into the boiler furnace of the coal power plant. Thecrushed coal is feed into a coal mill or coal pulverizer or coal pulverizer via a hopper, so the coal can be transported to the bottom of the coal mill or coal pulverizer or coal pulverizer, where the crushed coal can be grind into coal particles by the coal pulverizer. During the grinding process, hot air was flowed to the coal mill or coal pulverizer or coal pulverizer in order to dry the coal particles and lift the coal particles out of the coal mill or coal pulverizer or coal pulverizer and into the boiler furnace of the coal power plant. When the coal particles is too heavy, it will drop down into and be grinded again by the coal pulverizer.
